You must understand that a startup should be "sacred" for founders.You don't go on this quest just for money/fame or any other superficial reason.There needs to be a synergy and passion in the team.Of course no startup is without problems but some things must come naturally.

Lack of communication outrageous me honestly.I've seen this over and over again.It is extremely important to have good communication.Plus the fact that he works is another downside here.A successful startup needs dedication.
